In the present study, the behavior of hemispherical glass fiber-reinforced plastic (GFRP) energy-absorbers under applied compressive load has been investigated experimentally and numerically. A thermosetting general purpose polyester resin, along with bi-directionally woven E-glass fiber mats, has been used for the fabrication of the test specimens. Previously a limited number of studies were reported for hemispherical features made of composite laminates with fabrics based on randomly oriented chopped glass fibers. A motivation behind the current study is that woven fabric mats with continuous bi-directional strands can be considered as more reliable in terms of consistency of properties when compared with glass mats with randomly-oriented discontinuous fibers. Additionally, the current concept of dome-shaped composite entities has been explored for vehicle safety applications, which has not been done earlier.
